C'mon, if I can't remember the exact syntax, I'll just use the Mongo shell and copy-paste until it works. Who needs to memorize this stuff?

Hah, these questions are like trying to remember the 'correct' way to ask your dog to roll over. MongoDB has a steep learning curve!

A) db.test.push({x:2,y:apple},) is not valid. push() is used to add an element to an array, not insert a document.

I'm not sure, but I think option A) db.test.push({x:2,y:\'apple\'}) might also be valid because push is used for adding elements to an array in mongodb.
